Letters Patent No. 112,663, dated March 14, 1871.` l

` l `IMPROVEMENTIN BROADCAST lSEEDERS `AND CULTIVATORS COMBINED.

The' chedule referred` toin'these Letters Patentfan making part of the same.

in the county'of .WaliivorthA and State of Wisconsin, havev invented a new' and` useful `Improvement in Broadcast Seeder and Oultivator; and I do hereby de- `clare that the following is a'full, clear, and exact description thereof', which will enable others skilled in the `art/tol make and `use thelsame, reference being had `to theaccompanying drawingforming `part of this l speciication, in'rwhich- Figurel is a detail vertical section ot' my improved `machinetaken through the line x w, tig. 2.

r Figure `2 is adetail vertical section of s the saine Figure4 is a detail section taken through the line Similar'letters of 'reference indicate corresponding ',parts.` l l f My invention has `for its `object to furnish an im-v proved machine, simple in construction,` elfective in operation, and easily `inierated, and which shall be so i 4constructed asto adapt it for use as a broadcast seeder or ci1ltivator,` as may be desired; and

It consistsin the construction and combination of various parts of the machine, as" hereinafter more A isthe seed-box, thefront board of which is made `v.=.rtioal,.and the bottomand rear side are made in l clined, as shownin-g..2,l so as to cause the seed to l 4pass down freely into `the angle between lthe front side `amdbo'ttoni, of the said seed-box and i `seed from bridging or clogging.

The ends Bof the box Aare cast, and have grooves or` flanges formed inthern `to receive the ends of the front,` bottom, andv real; boards of the seedfbox A.

` :The seed-box A is strenothened b one two or l more cross-partitons, O, by a long `bolt, D, passing e Ithrough the ends B of said `box`A, and by the crossboltsE passingthroughI the front and rear sides of `said box.. By this construction the seed-box is made so strong that no frame is required to support it.

i y )Upon the endpiecesB are cast the hollow axles F,

upon which "the hubs lof the wheels G work, as shown i H is the tongue, thefrear end of which` issecurely attached tothe middle partei' the seed-box A, and

prevent the Sach other.

with which the end partsof the box A are connected `The endl parts of ,theWcross-bar I are connected i `'with the tongue H by the bracesbars K.

` II are `brace-rods, the lower ends orf which are secured to the tongue H, and the upper ends of which are secured -to the endsof the cross-bolts E, y In the angle between the front ahd bottom boardsV 'of the box A is secured apipe, M, which serves as a continuation of the hollow axles F, as shown in iig'. 1.

In the upper side of the pipe M are formed several' holes m1, for the seed to enter the pipe M, and in the' lower side of the said pipe, at suitable distances apart,

in' positions not directly beneath the ingress openings, are formed egress openings m2, through which the seed escapes from said pipe to the ground.

N is a rod, extending through the pipe M and hollow hubs, F. from side `to side 'of themachine, upon which are formed screw-threads by winding a wire of suitable form and size spirally around `the said rod,

or by cutting the said thread upon the rod, or in any l' other convenient manner. Y

To the bottom of theseed-box A, around the discharge-openings mz of thepipev M, 'are secured the seeds from the spouts O fall,.and byv which they are scattered.

Q are the cultivator-teeth, the-upper ends of the shanks of which are bent over to form an eye.

R are two washers, the inner edges of which are .beveled off, as shown in g. 4, and upon the outer sides ot' which are formed shoulders to receive the rear ends of' the two beams S. Y `The washers R are placed one upon each vside of the eye of the shank of the plow Q, and the washers and eye are placed between the rear ends of a pair of beams, S.' Y 4 p Abolt, T, is then passed through the eye, washers, andbearns, securely clamping the said five parts to By this construction the plows may be secured tothe beams` with any desired strength, and,

`at the Sametime, in such a way that, should the plow strike an obstruction, it will be turned hack instead of being broken. Y

The forward ends of each pair of beams Sere hinged to the cross-bar I by means of -a long staple, Ul, and a strap or claspfUZ.

To the rear` ends of the cross-bolts E are attached the brackets V, to which are pivoted the ends of a roller, XV, to the center of which is pivoted a lever, X.

To the lever X, upon theppposite .sides-of its pivoting point, 4and equally distant from said pivoting point', are attached theends of two ropes or chains, Y, which pass oveiguide-pulleys Z, pivoted to the outer sides ot' theends of the bracketsV,-and their lower ends are attached to the cross-bar A', which extends across the machine beneath the rear parts of all the beams S, so that, by operating the lever X, the plows may be raised from and lowered to the ground, as may be required. The bar A is held in proper position with reference to the beams S by the rods L', the4 To one of the brackets V is also attached a vertical' catch-arm, C', to receive and hold the lever X, when the plows are raised, in such a position that it may be conveniently reached and operated by the driver, when riding upon the'corer lc' of the seed-box A. In this case the lever X, when the plows are in working position, restsupon the other bracket V. v To the outer end of the screw-rod N, that projects beyond the hub ot' the wheel G, is attached a conepnlley, D', the inner end of which should he recessed to receive the outer end ofthe hub ofthe wheel To the inner end of the hub of the wheel G is atas'shown in iig. 1.

' l1" is an endless chain, which passes around thev cone-pulley E' of the wheel G, over a pair of guidepulleys, G', suspended above the wheel G, and around the cone-pulley D', of the screw-rod N, so that the said screw rod may be revolved to feed the seeds to the dischargeopenings fm, ol' the pipe M by the advance of the machine.

The block of the pulleys G' is suspended from the upper end of the lever H', which is pivoted toa pin attached to the end B of the seed-hox A.

The lower end of the lever H projects in the'rear of the seed-box A, and to it is attached the end of a coiled or equivalent spring, l', the other end of which is attached. to the end B of' the box A.

The spring I should have suiicient strength, to hold the chain or baud F snciently taut to revolve the screw-rod N.

To the rear part-ot' the lever H' is pivoted the upper` end of a rod, J', which passes down through a hole in the end ot' the bar A', and has a collar, K', adjnstably secured to it by a set-screw.

By this construction, when the bar A' is raised to raise the plows from the ground, the said bar A strikes against the collar K', attached to the lever H', and raises the rear end of the lever H'; this siackens the chain F', so that the advance of the machine will not revolve the rod'N.

Having thus described my' invention,

I claim as new and desire to secure by Letters Patent l. The hollow axles F, cast solid with the ends B of the seed-box A, substantially as herein shown and described, and for the purpose set forth.

2. The cone-pulley E'fast to the hub of the wheel, the endless chain F', and the pulley D', fast to the end of screw-rod N, all combined as described, furthe purpose of revolving the latter as the vehicle moves forward.

3. The combination of' the brackets or supports V, shaft W, pivot-ed lever X, chains Y, and cross-bar A' with each other and with the plow beams S, substantially as herein shown and described, and for the purpose set forth.

4. rI he spring I', pivuted lever H', and pulley-block of G', combined', as described, with the band F', for the purpose of holding the latter in sufficient frictional contact with the pulleys to rotate the screw.

5. The rod J', passing loosely down through-bar A', and collared at-K', above it, combined, as described, with lever H', to allow the elevation of ,said bar A to raise the end of lever, slacken the chain, and stop the rotation of screw, as set tortli.

vLYMAN WIGHT.
